The mouse pad in my opinion is pretty useless and I do not understand why no reviews of umlaufene bead is mentioned. More than 1-2 stars I can not understand for the pad. The problem is that (See macro shot) surrounds the mouse area a little bead. When using the mouse, I use a MX518, the bead / rim of the pad is a resistor must be overcome by the mouse "on" to push this bead. Especially when sensitive Slide if you want to make a menu item, it will be difficult. Add to this the fact you mouse anyway because you have to have more forward otherwise continuously abuts the rear. This inevitably leads to the edge / bead is also indicated by the mouse forward and backward only about 1.5cm square (see picture with your mouse) has. In a normal "rimless" pad that would be no problem since one of the sensor may postpone necessary with the mouse over the edge since is centered under the mouse you so enough "reserve" has.
+ Positive is the gel pad is soft without being too soft + It is completely washable since both silicone body and mouse surface made of plastic
- Something small, only 1.5 cm space, front and rear (see picture with your mouse) - Circumferential bead (see Macro) - The gel pad is breathable "inactive" which makes it easy sweating wrist
If the area would be a bit bigger and not have a peripheral bead I could get used to the pad. But it is also thanks to blister, a case for the circular tray.
